Yes Western archers used hip quivers. It also depends on what you're doing along with personal preference. I'm glad from 2.0 on XIV stopped being like XI in the need for ammo department. I would hate to need to carry around 2 full stacks of 99 arrows in XIV just to be able to do my job. Before they made stack numbers go higher. But yeah this is one of those things where it probably is best not to try to rationalize it.
